Precise Chemical Analyses of Planetary Surfaces
Author(s): Kring, David; Schweitzer, Jeffrey; Meyer, Charles; Trombka, Jacob; Freund, Friedemann; Economou, Thanasis; Yen, Albert; Kim, Soon Sam; Treiman, Allan H.; Blake, David; Lisse, Carey
Abstract: We identify the chemical elements and element ratios that should be analyzed to address many of the issues identified by the Committee on Planetary and Lunar Exploration (COMPLEX). We determined that most of these issues ...
NASA Center: NASA (non Center Specific) Publication Year: 1996
Added to NTRS: 2008-06-02
Accession Number: 96N34812; Document ID: 19960051149
Electron Spin Resonance (ESR) studies of returned comet nucleus samples
Author(s): Tsay, Fun-Dow; Kim, Soon Sam; Liang, Ranty H.
Abstract: The most important objective of the Comet Nucleus Sample Returm Mission is to return samples which could reflect formation conditions and evolutionary processes in the early solar nebula. It is expected that the returned ...
NASA Center: Jet Propulsion Laboratory Publication Year: 1989
Added to NTRS: 2008-05-30
Accession Number: 90N16651; Document ID: 19900007335
Electron Spin Resonance (ESR) detection of active oxygen species and organic phases in Martian soils
Author(s): Tsay, Fun-Dow; Kim, Soon Sam; Liang, Ranty H.
Abstract: The presence of active oxygen species (O(-), O2(-), O3(-)) and other strong oxidants (Fe2O3 and Fe3O4) was invoked in interpretations of the Viking biological experiments and a model was also suggested for Martian surface ...
